JBJ Reaction HOB Hang-On-Back Aquarium Filter HB-15 — Powerful 3-Stage Filtration for 20 Gallon Aquariums
The JBJ Reaction HOB Hang-On-Back Aquarium Filter HB-15 is a slim, efficient hang-on-back power filter engineered for freshwater and saltwater aquariums up to 20 gallons. The JBJ Reaction HOB Hang-On-Back Aquarium Filter HB-15 delivers complete 3-stage mechanical, chemical, and biological filtration through an innovative dual intake system that combines a standard bottom intake with a self-leveling surface skimmer — simultaneously filtering the water column and removing the oily surface film, sludge, and floating particles that standard single-intake filters leave behind. The adjustable flow control valve lets you customize water movement for any aquarium inhabitants, and the waterfall-style outflow promotes healthy oxygen exchange and CO2 diffusion. The JBJ Reaction HOB Hang-On-Back Aquarium Filter HB-15 hangs compactly on the back of the aquarium with a slim profile that keeps the aquascape unobstructed.

JBJ Reaction HOB Hang-On-Back Aquarium Filter HB-15 — 3-Stage Filtration System
Stage 1 — Mechanical Filtration
The dual intake system draws water from both the water column and the surface simultaneously. Combination fine and coarse sponge filters capture particulate matter, detritus, and suspended solids. The coarse pre-filter sponge protects small inhabitants while providing initial mechanical filtration before water reaches the media chamber.
Stage 2 — Chemical Filtration
Activated carbon removes dissolved organic compounds, tannins, odors, and discoloration — maintaining water clarity and chemical stability throughout the aquarium.
Stage 3 — Biological Filtration
Ceramic rings provide extensive internal and external surface area for colonization by beneficial nitrifying bacteria — supporting a stable nitrogen cycle and healthy water chemistry.
